Yes, definitely - this is all based on the "adjusted close" values from yahoo's historical data feed. This is interesting - I've shared this multiple times in other discussions like this, and a comment like yours is always the first response, that it seems low, questioning if I included dividends. If anything it might just underscore how our collective "societal" intuition might be a bit off in terms of long term retirement performance. I think part of it is that people tend to contribute more to retirement when times are good, since they have the extra money, and contribute less when times are bad since they're just getting by. The problem is that the market tends to be high when times are good, and low when times are bad. So this will naturally depress performance for everyone. It's impossible to contribute a consistent amount every week/month without having a cash buffer (which would depress performance anyway).
